Description
Technical field
The utility model relates to a kind of mains switch, especially relates to a kind of safe and reliable pressure and breaks off rocker switch.
Background technology
To using the equipment of rocker switch in big electric current inductive load, electric tool load and the capacity load as mains switch; Because inductive load and electric tool load equipment can produce the impulse current of 6 times of about rated current when starting; And capacity load has the discharge impact electric current, and (impulse current is relevant with capacitance; Be directly proportional), produce arcing, high temperature; When immediate current is very big, the moving point of switch and dead point sintering phenomenon together can appear, make the switch cisco unity malfunction, when closing external power supply, after the decline of switch internal temperature, switch can be worked again, but also the silver point sintering phenomenon can occur during follow-up work.
Summary of the invention
The purpose of the utility model is exactly to provide wide, the safe and reliable safe and reliable pressure of a kind of scope of application to break off rocker switch for the defective that overcomes above-mentioned prior art existence.
The purpose of the utility model can realize through following technical scheme: rocker switch is broken off in a kind of safe and reliable pressure, it is characterized in that this rocker switch comprises pressure button cover, push-button socket, shell, rotation axis, movable contact spring, moving contact, pressure bar, edge joint haptic element, fixed contact, middle contact feet, base, slide cartridge or steel ball; Described pressure button cover cover cap is on push-button socket, and pressure button cover and push-button socket are positioned at shell, and described push-button socket has slide cartridge or steel ball; Described pressure bar center is arranged on the rotation axis, forces bar one end to connect push-button socket, the other end and movable contact spring matched in clearance; Described moving contact is arranged on the movable contact spring, and described fixed contact is arranged on the base, and with its top movable contact spring be oppositely arranged; Described edge joint haptic element is arranged on the base two ends, and described middle contact feet is arranged in the middle of the base, to the pressure button cover application of force; The drive push-button socket rotates, and rotates thereby drive with the close-fitting pressure bar of push-button socket, forces bar to turn to the contact movable contact spring; When silver point clings; Force bar to promote movable contact spring by force, moving contact and fixed contact are separated, force to break off rocker switch.
There is a boss described push-button socket below, and this boss closely cooperates with forcing bar.
Described rocker switch also is provided with lamp base and luminous element, and described lamp base is arranged on the base, and described luminous element is arranged in the cavity of pressure button cover and push-button socket formation.
Described slide cartridge or steel ball lower end butt movable contact spring, and can on movable contact spring, slide.
The top of described pressure button cover exposed parts is plane, V-arrangement face, arcwall face, arc millet cake light or waterproof arcwall face.
Compared with prior art, the utlity model has following advantage:
One, the scope of application is wide: rocker switch in the market all is to adopt lever principle; For little electric current≤4A (non-resistive load), or more satisfactory structure, but for electric current 4A＜I (non-resistive load); Still can occur to break off phenomenon behind the silver point sintering; After this improved, the dissatisfied fully silver point sintering of determining can not break off phenomenon, makes switch play the operate as normal effect;
Two, safe and reliable: as to force disconnection can effectively prevent to combine to cause equipment fault and security incident in the invention because of the contact.
